From Booklist
This sequel to
The Castle of the Silver Wheel has the vice of not being terribly intelligible if you don't know the first book; indeed, it practically demands a genealogical chart. Otherwise, it's a fine exploration of the situation that arises when a kingdom comes under a curse and an heir must be found to do penance for his father's sin--but nobody knows what the sin was or where the heir is! Gwenlliant and Tryffin, wed at the end of the first book, are now exploring the full range of their powers and becoming deeply involved in the search for the heir. A well-told tale that captures the Celtic faerie atmosphere in all its beauty and confusion.
